An energy storage element for providing a voltage has a first control apparatus and modules, which modules each have an energy storage unit, a connection unit and a module control apparatus. The connection units are connected between two associated modules and have first switches and which connection units are designed to enable, on the basis of the state of the first switches, at least two connections from the group of connections including parallel connection of two modules, serial connection of two modules, bridging of at least one of the two modules which first control apparatus and which module control apparatus are together designed to make it possible to change the control of the associated connection unit during use of the energy storage element in order to reconfigure the energy storage element. The first control apparatus is designed to control the module control apparatuses.
